This invention relates to the former of a printing press.

The principal objects of the invention are to provide an extra former orformers in such relation to the usual duplicate formers as to avoidduplication of the drag roller, slitter, and propeller mechanism, thusreducing the expense very materially; to provide an arrangement in whichthe over head space will be reduced, so that an additional former orformers can be used in rooms not sufiiciently high to receive the usualconstructions; to provide an arrangement by which the leading of the webaround several rollers between the upper and lower former carriages willbe avoided, thus eliminating the creasing of the web by that means; toprovide means for avoiding the usual creeping of the tabloid Webs oneover another in the old constructions; to provide means for eliminatinga slot through which the webs must be led; to provide means for leadingthe web in just as'easy a manner as though there were no extra formers,to avoid the so-called bay-window which the web has to make around theside of the ordinary duplicate formers when an extra former has beenused heretofore; to provide for employing this inven tion with tabloidsheets, and to provide for lead ing the webs in the manner abovedescribed from presses out of line with the original line of presses.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanying drawings, in which Fig. 1 isa side view showing a plurality of webs coming from a press or series ofpresses into the folder and showing the preferred em bodiment of thisinvention;

In the association of products from a printing press in high speedproduction it is often desirable to produce products of more than onesection. In order to produce two sections, the folder may be run collector the product may be run over two formers and brought into a singlefolder running straight. This latter is called a transverse run.

It is often desirable, however, to print a prod not of three or foursections. When this is to be done it is customary to place an extrasingle or double former above the regular ones and to run a number ofWebs to them. After these webs were given their full-page folds thepaper would be run around several rolls at the sides of the usual doubleformers, making what is called a bay-window run to a point below theordinary double formers. There they would be collected, together withthe products coming through the usual formers, and delivered into thefolder. This would make a newspaper having t ree, four or six sections,depending upon the number of extra formers used, and Whether straight orcollect papers were being run.

This arrangement has been open to a number of objections. In the firstplace, the placing of one or two formers above the usual ones requires aconsiderable amount of head-room. For that reason this arrangement couldnot be used in many press rooms. A complete duplication of the dragroller, slitter, and propeller mechanisms was necessary in the oldconstructions for the upper former group. This practically doubles theexpense of this part of the press.

In order to provide these extra webs in the way that is mentioned, spacehad to be provided between the two former groups, so that there would beroom for running the webs from in front of the folder to the rear of thefolder in either one of the former groups. The wasting of this spacemakes the leading of the webs quite difficult. The folded webs having togo around several rol1- ers between the upper former carriage and thelower become badly creased in their passage. In the running of a tabloidit has been almost impossible to prevent some of the sheets fromcreeping over the others.

By this invention the extra former or formers are placed in line with,and on the same level as, the customary double former with provisionsfor leading the web, of course, to these extra or auxiliary formers. Inthis way as many webs as desired are led over turning bars placed out ofline with the regular formers. These Webs are then led over either orboth of the extra formers, and after being folded page size aretransverse collected and led into any of the folding and cuttingmechanisms provided. The extra press unit is placed in front of theformer from which the web is passed over a slitter roll, half of the webon each side going over angle bars to the auxiliary formers. In thiscase the webs can all be brought over a single drag roll, and althoughthat is made extra long, there is only one mechanism for operating it.

In Fig. 1 are shown diagrammatically the course of several webs comingfrom what may be considered the usual press or line of presses 9 overand under guide rolls 10 to the drag roll 11 and from that to the doubleformer 12. The double former, as usual, consists of two formers adjacentto each other for receiving the slit webs from the drag roll anddelivering them to the folder rolls 13 and in this case to two sets ofnipping rolls l4 and 15 which fold and crease the webs longitudinally.The nipping rolls 15, as usual, deliver the folded webs to the foldingcouple 16 of the folding machine shown diagrammatically. As so fardescribed this is the ordinary procedure.

When additional webs are to be introduced they can come from a press 17in this case shown as located on the opposite side of the folder fromthe press 9 but in line with it, where they pass over guide rolls 18 andturning bars 19 to divert them beyond the sides of the first named websand bring them over guide rolls 20 to the same side of the drag roll asthat on which the guide rolls 10 are located so that all the webs passover the drag roll in the same direction. These webs, however, from thepress 1'? pass beyond the sides of the webs from the other press and allin the same plane. lf'hus only one drag roll is required and only onemechanism for operating it.

For providing tabloid sheets slitters 21 are placed over each former orover any of them. Slitters are also shown in connection with each press.

In this case extra formers 22 are employed. Of course, it will beunderstood that only one of these would be used if a smaller paper is tobe produced. From the single or the two formers 22 the web or webs passthrough the folding rolls and the nipping rolls 24 associated with theseformers and then to the pair of nipping rolls 15 previously describedand then into the folders as usual.

In this case two courses of the webs are illustrated. One set of dottedlines in Fig. 3 illustrates the path of the webs when the three righthand formers are feeding their webs into the left hand folder on oneside and the other set of dot and dash lines shows the three left-handformers feeding into the right-hand folder. The full lines represent thetwo right-hand formers feeding into the right-hand folder and the twoleft-hand formers feeding into the left-hand folder. This provides avery desirable means whereby any one of three formers may feed webs intoeither of the folders.

In Fig. i the extra press 26 is shown out of line with the presses 9 andperpendicular to them. In Fig. 5 arrangement is similar, the extra pressnot shown) being out of line, but parallel with the original presses 9.

Economy in this construction over the previous ones is obvious sincethere is only a single drag roller, although it is longer, and only asingle means for operating it is used. The need of addiional space forthe folders located above is eliminated. A little additional width isrequired but only a little as a printing press of the modern type isconsiderably wider than the web used therein.

It will be seen that when running straight papers, they may be deliveredin two, thr e or four sections and when running collect in four, six oreight sections depending, of course, on how many formers are in use.

Although I have illustrated and described only three embodiments of theinvention I have indicated that instead of four formers, three can beused, the extra one being located on either side of the usual formers,and I am also aware of the fact that other modifications can be madetherein by any person skilled in the art without departing from thescope of the invention as expressed in the claims. Therefore, I do notwish to be limited in this respect but what I do claim is:-

1. In a printing machine, the combination with a-drag roll and a doubleformer, of an extra former located at one side of the double former andin horizontal alignment therewith and in position to receive the webfrom another press over the same drag roll.

2. In a printing machine, the combination with a drag roll, a doubleformer and a pair of folders located in position to receive the productsdirectly from the two parts of the double former, of an extra formerlocated at the side of the double former and having means for deliveringits prodnot to either one of said folders and in position to receive theweb over the same drag roll.

3. In a printing machine, the combination with a drag roll, a doubleformer for receiving the slit web from a printing press, and a pair offolders each located in position to receive the products from one f theparts of the former, of an extra former located at the side of the firstnamed formers and in alignment therewith, a second press means fordirecting a web from the second press over said drag roll to the extraformer in the same direction as the webs delivered to the double formerand means for guiding the products from the extra former to eitherfolder.

In a printing machine, the combination with a drag roll, and a doubleformer positioned to receive a slit web over said drag roll, of an extraformer located in position to receive the web from another press oversaid drag roll.

5. In a printing machine, the combination with a double former, and adrag roll in position to deliver a slit web from a printing press oversaid drag roll to the double former, of a second printpress, leans fordelivering a slit web from the second printing press in two lines at thesides the path of the first named webs to a point at the back of saiddrag roll and a pair of formers located at opposite sides of the doubleformer and in alignment therewith in position to receive the slit websfrom the second printing press over the same drag roll at points beyondthe outer edges of the double former.

6. In a printing machine, the combination with two presses located inline, of a single drag roll, a double former positioned to receive aslit web from one press located in line with said formers, and an extraformer located in position to receive the web from the other press.

7. In a printing machine, the combination with two presses located outof line and perpendicular to each other, of a single drag roll, a doubleformer positioned to receive a slit web from one press located in linewith said formers, and an extra former located in position to receivethe web from the other press.

8. A plurality of presses and a pair of formers arranged in linetherewith, in combination with an extra former, located out of line withthese presses and formers, and means for conveying the web from certainof these presses over the extra former and for associating the foldedwebs from all formers into a single folding mechanism.

9. In a printing machine, the combination with a drag roll, and a doubleformer positioned to receive a slit web from said drag roll, a pair offolders located in position to receive the products directly from thetwo parts of the double former,

of two extra formers located one at each side of said double former andeach having means for delivering its product to the adjacent one of saidfolders.
